Chapter 4 Building Business Process Diagrams

Introducing Business Process Diagrams

A Business Process Diagram (BPD), sometimes known as a Process Flow Diagram (PFD), graphically represents the dynamic behavior of a system, how its objects interact, and who does what at run-time.

A business process diagram can be created in a model, a package or within a decomposed process.

There are three types of BPDs for modeling different aspects of a system:

Top-level diagram – focuses on the roles played by business partners in relation to a system (see Top-Level Diagram Basics)
Choreography diagram – focuses on allocating responsibility for activities, choreographing objects, analyzing flows of data, and modeling the implementation of activities (see Choreography Diagram Basics)
Data flow diagram – focuses on data exchange between processes (see Data Flow Diagram Basics)
